* reader: milliseconds spent reading sample data over USB from a SDR dongle
* background: milliseconds spent doing network I/O, processing received network messages, and periodic tasks.
* cpr: statistics about Compact Position Report message decoding. Has subkeys:
* surface: total number of surface CPR messages received
* airborne: total number of airborne CPR messages received
* global_ok: global positions successfuly derived
* global_bad: global positions that were rejected because they were inconsistent
* global_range: global positions that were rejected because they exceeded the receiver max range
* global_speed: global positions that were rejected because they failed the inter-position speed check
* global_skipped: global position attempts skipped because we did not have the right data (e.g. even/odd messages crossed a zone boundary)
* local_ok: local (relative) positions successfully found
* local_aircraft_relative: local positions found relative to a previous aircraft position
* local_receiver_relative: local positions found relative to the receiver position
* local_skipped: local (relative) positions not used because we did not have the right data
* local_range: local positions not used because they exceeded the receiver max range or fell into the ambiguous part of the receiver range
* local_speed: local positions not used because they failed the inter-position speed check
